Specification of Letters Patent.

T all whom it may concern:

Be it known that I, FRANTS CHRISTIAN STooKEL, of V0. 72 Ryesgade, Copenhagen, in the Kingdom of Denmark, mechanical engineer, have invented certain new and useful Improvements in Bottle-0losures; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The present invention relates to an improvement in that class of bottle closures which comprise a closing plate adapted to be placed over the mouth of the bottle, the said plate being provided with hooks which engage from below a collar, shoulder, or the like, located on the neck of the bottle. In bottle fastenings of this kind. hitherto known, the said hooks are formed by simply bending the arms of the plate inward, that is to say, in a direction toward the bottle, at their lower ends (see Figure 9). The capability of resistance of a hook so formed against bending strains depends exclusively upon the bending strength of the material, and since this strength is a, relatively small one, the hooks may become automatically disengaged or unlastened, for example during the pasteurizing or sterilizing oi' the contents of the bottle, which would result in the opening thereof.

In the closure constructed according to the present invention the hooks are formed by first bending outward, and upward, and then inward the lower ends of the downwardly extending arms, as shown in Figs. 10 and 11. A hook thus formed will engage the collar the more firmly, the greater the upward pull on the arms.- The improved closure will therefore offer great resistance to unintentional or accidental opening and during pasteurizing will insure the bottle keeping tightly closed and therefore enable a wire fastening to be substituted.

In the drawings, in which like parts are similarly designated'Fig. 1 is a side elevation; Fig. 2 an elevation at right angles to F ig. 1 of a bottle having one form of my invention applied thereto; Fig. 3 is a plan view of the closure before being applied to the bottle 3 Figs. 4 and 5 are elevations at right I angles to one another of a modification; Fig. 6 is a bottom plan view of the cap shown in Figs. 4 and 5; Fig. 7 is aplan view of another modification; Fig. 8 is a section on line A-A of Fig. 7 Fig. 9 is a diagrammatic view of an old form of closure; Figs. 10 and 11 are diagrammatic views showing the manner oi engagement of my improved closure with the flange or bead on the bottle neck.

In the form of construction shown in Figs. 1 to 3, the closure consists of a circular plate or disk a of suitable metal and of a diameter somewhat larger than the diameter of the bottle mouth. The said plate or disk (1, is provided with two or more radial arms I), the lower ends of which are provided with pointed parts 0 extending on both sides and which are bent outwardly and upwardly, so that said parts bear against the outer sides of the arms, when the closure is applied to the bottle. The points of said parts 0 are bent inwardly and engage below the collar or I shoulder (Z on the bottle neck, thus effecting the closure, that is to say, they force the plate against the bottle mouth and hold it firmly in place.

In the operation of closing the bottle a disk f of cork or another suitable elastic material is placed on the mouth, whereupon the plate a is placed over the disk f and the arms I) bent downward on the bottle neck, after which the parts 0 are bent inward in such a manner, that the points thereof engage below the collar d, and the elastic disk f is compressed by means of a plunger or the like acting on the plate a. Owing to the use of a disk f of elastic material, any slight irregularities in the shape of the bottle mouth do not prevent a tight closure being effected. It is evident that in the same ratio as the pressure increases in the bottle and acts on the plate a from the interior the parts 0 grip the tighter below the collar d.

In the form of construction shown in Figs. 4 and 6, that part of the closure which lies on the bottle mouth is bent as at 1c in such a manner that a cap is formed. In addition a form of bottle neck or collar d is shown in Figs. 4 and 5, which is preferred to that shown in Figs. 1 and 2, since said collar is undercut at Z (see Fig. 11), thus enabling the points of the parts 0 to find a better hold.

For opening the bottle no special means or tools are required, such opening being effected by hand by bending one of the arms 6 outward from the bottle neck. This can be suitably done by a penknife, coin, or any convenient article or implement.

In the form shown in Figs. 7 and 8 the arms I) are each provided with buta single wing or point 9 which is bent outwardly and upwardly and passes through an aperture It provided in the arm I). This form of closure, the central part of which can also be formed as a cap 7f, acts in the same manner to those shownn'n Figs. 1 t0 6.

Instead of the closing disk f a tightening ring or similar body may be used and the central part a or 76 of the closure can be so shaped that it holds said tightening body when the latter arranged either on or in the closure.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A sheet metal bottle closure comprising a central portion adapted to cover the mouth of a bottle and arms extending from said central portion whose ends are bent outwardly and folded upon themselves, said ends being provided with engaging points extending toward the bottle neck and beyond the arms.

2. A sheet metal bottle closure comprising a central portion and a plurality of arms extending from said central portion, the ends of said arms being bent outwardly andfolded upon themselves, said folded portion being provided with bottle engaging points expresence of two subscribing witnesses.
